The single-channel Jensen Transformers Iso-Max VB-1BB is a passive, 75-Ohm isolator for composite (baseband) video, which prevents and eliminates hum bars caused by 60-cycle ground loops. It ensures that the video signal is faithfully delivered without noise, contamination, or artifact, even where ground voltage differences are very large such as in surveillance video systems, night clubs, video walls, broadcast stations, or industrial plants.
The VB-1BB combines 75-Ohm BNC connectors with a custom-wound Jensen transformer. This precise impedance-matched circuitry ensures minimal reflection while providing an exceptionally linear bandwidth from 10 Hz to 10 MHz, with 120 dB of ground noise attenuation.
Easy to set up with no power required, the Iso-Max VB-1BB is housed in a rugged steel enclosure fitted with screw-down flanges for easy installation in 19" racks, inside a NEMA enclosure, under shelves, or for attaching to cabinetry.
